CIRCULAR-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 380,385, dated April3, 1888.

Application filed October 10. 1857. Serial No. 251.902. (No model.)

To all whom it may concern.-

.Be it known that I, HENRY GURTrN, of Little Falls,in the county ofI-Ierkimer,in the State of New York, have invented new and usefulImprovements in Circular-Knitting Machines, of which the following,taken in connection with the accompanying drawings, is a full, clear,and exact description.

This invention relates to the class of knitting-machines in which atubular circular head is rotated on the bed-plate of the machine andcarries on its periphery the knitting-needles in vertical positions.Said machines are designed for knitting cylindrical fabrics, and theknitting of cylinders of different diameters requires needle-carryingheads of corresponding varying diameters. For this reasoninterchangeable needle-carrying heads of different sizes have beendetachably connected to the bedplate and driving-gear.

My invention consists in an improved construction and combination ofsaid parts,whereby the same is simplified and the attachment anddetachment of the needle-carrying head is rendered more convenient andthe wear of its journalbearings is materially reduced, all ashereinafter fully described, and specifically set forth in the claims.

In the accompanying drawings, Figures 1 and 2 are partly side elevationsand partly vertical transverse sections of needle-carrying heads ofdifferent diameters and their connection with the bed-plate anddriving-gear embodying my invention.

' A represents the bed-plate, which is usually mounted on standards or asuitable supporting-frame, not necessary to be here shown. Saidbed-plate is provided with a circular eye, 0, and with an annularrabbet, or, around the top edge of the eye. In said eye and rabbet arepivoted the head D and its drivingpinion G in the following manner: Thesaid pinion I form with an upward-projecting hub, Z, which is journaledin the eye 6 and terminates flush with the base of the rabbet a, andupon the top of the hub Z, I mount the head D, which has its To protectthe base of the head D from wear by friction on the base of the rabbet,I interpose between the base of said head and top of the hub Zawear-plate or anti-friction metal ring, I), which also projects into therabbet to serve as a bearing for the base of the head D. a

By means of screws t t, passing vertically through the hub of thegear-wheel or drivinggear 0, and through the wear-plate a nd into thewall of the head D, the head is firmly secured to the gear 0, and theweanplate clamped be tween them.

In connection with one and the same set of bed-plate A, gear O, andweanplate Z), I employ interchangeable heads D D, of different sizes andwith bases of uniform external diameters and corresponding screw-tapsfor the reception of the screws t t, which permit a ready attachment anddetachment of the interchangeable heads.

What I claim as my invention isl. The combination of the bed-plate A,provided with the eye 6, and rabbet a, around the top edge of the eye,the pinion G, formed with the upward-projecting hub Z, journaled in theeye e, and the head D, seated upon the top of said hub and having itsbase fitted rotatably in the rabbet a and detachably connected to thehub Z, substantially as set forth.

2. The combination, with the bed-plate A, provided with the eye 6 andrabbet a, of the gear-wheel 0, having the end of its hub flush with thebase of the rabbet, the head D, detachably connected to the hub of thegearwheel and having its base projecting into the rabbet a, and thewear-plate b, clamped between the end of the wheel-hub and base of thehead and projecting into the aforesaid rabbet, substantially asdescribed and shown.

In testimony whereofl have hereunto signed my name, in the presence oftwo witnesses, at Little Falls, in the county of Herkimer, in the Stateof New York, this 6th day of October, 1887.
